- Family-flag fan-out is real.
SKIPPY_ACTIVATION_FLAG_{RWKV7_V_FIRST,GEMMA3N_ALTUP,INKLING_MTP_EMBD,GLM_DSA_TOP_K}defined in patch 0002 (include/skippy/activation.h), KIMI_K3_RESIDUAL added by 0039. Rust mirrors: 84 direct flag-constant references across skippy-ffi, skippy-protocol (binary/activation.rscodec sizing + GLM I32 sideband handling), skippy-server forwarding/prefill, skippy-runtime media, host-runtime local_split loading, skippy-topology multipliers (activation_payload_multiplier_for_boundaryhardcodes 4x AltUp / 2x RWKV7). Order of magnitude matches scama's 171/17 count. - The planner frontier exists and is verified. Patch 0005 (
stage_slice_plan.cpp,graph_identity.cpp) computes `activatio
